This long-standing article has had numerous sourcing problems for a number of years. I just made a careful examination of possible sources written about this topic and found way too insufficient coverage to warrant an article on the subject. The article appears to have served, from time-to-time, as a coatrack for a website entitled "Water UFO", an originally researched list of UFO-incidents that may have involved water in some way, and an inappropriate conglomeration of trivia. One of the most reliable sources related to this article is a TIME magazine piece from Feb. 22, 1960 stating, rather whimsically, that every time naval appropriations is discussed in the Argentine Congress, an unidentified foreign submarine is reported to have been spotted in Argentine waters. "Unidentified submerged object" doesn't appear in the article. A search through Google scholar has uncovered almost no discussion of the term as a notable idea, and any mention of it at all is either a minor consideration or almost completely off-handed. Strictly speaking, I think we have a fringe subject not warranting inclusion. Note, for example, that the History Channel did a special on "Deep Sea UFOs" and did not call them "USOs". This is telling: even the pop-culture coverage of these ideas do not agree on collating them under this term.
We should include reports of UFO-like sightings associated with bodies of water (and under bodies of water) in articles on the UFO phenomenon, but a separate article on USOs is impossible to write given the paucity of sources which actually deal with the subject as written here at Wikipedia. Right now, this article is actually serving as a verification for the very existence of such a term: in effect, Wikipedia is being used to promote the idea that this is the way such objects should be labeled: [1] If there was ever a reason to delete an article, I think this is it. The last thing we need is for Wikipedia to become a primary source for paranormal entities. Let these concepts develop outside of Wikipedia and after third-party sources take notice THEN we should write the article. NOT before. ScienceApologist (talk) 19:07, 20 July 2010 (UTC)[reply]
